Paint/sealant on damp surface

[deuce22]

I am trying to channel water around the back and side of my foundations, so that I can start laying the ICF blocks and foam them to the concrete. I have screwed a 4x2 to the concrete and want to seal the joint. I have tried 3 different sealants and 4 different paint compounds. All have said that they can be applied on damp surfaces and some said even underwater. Not one of them has worked properly, they don't seem to be bonding to the damp concrete and has no chance of bonding where there is water.

 

The bank at the back and side is constantly releasing water, even after weeks of dry weather and I need some way of diverting this. Has anyone got any ideas to solve this or any product that actually does bond to wet/damp surfaces?

 

Thanks.

Is it possible to dig a trench on the other side of the foundation and fill with shingle like a French drain to divert the water?  With the joint, have you tried CT1?  Otherwise could you loosen the screws and put rubber strip under the timber?

I have used this PU glue with damp wood successfully but I haven't tried it with damp concrete.

Hi, 

Maybe this would work on damp concrete surface.
